Today's Tech: The bright side of London's tube strikes, a new Samsung Galaxy S4 and Google's political Sochi Olympics doodle

Every Tube strike has a silver lining

If you were one of the thousands of unfortunate commuters trying to get the London Underground to work over the last few days, you might not believe it - but not everyone sees the recent Tube strike as an unmitigated disaster.

We realised how many alternate forms of transport there are in London, for instance. When Tube strikes occur, we are forced to find alternative routes and transport to our offices. Since the current Tube strike, many have realised how close everything in London actually is.

Every Tube strike means more people will decide to walk to their office from their Overground stop even after the Tube strike because of their new knowledge of the London route.

Something to hold on to, perhaps, if the next planned strike goes ahead next week.

Samsung Galaxy S4 relaunched in jet black flavour

So the Galaxy S5 announcement is set for later this month, but you don't want one of those... what you really want is a Black Edition Galaxy S4. Right? Well, that's what Samsung has just announced, along with a black S4 mini to boot.

Samsung has revealed the new Black Edition model, which boasts a "premium" design. In other words, not only is it black, but it has a faux-leather textured rear cover and bezel.

This will certainly appeal to some as the S4's glossy plastic finish has come in for a fair bit of criticism, with many feeling that it's a very cheap finish for a high-end phone. The S5, of course, may well dispense with the plastic entirely and go with a metal chassis (quite possibly aluminium).

Google gets political with LGBT Olympic doodle

Search giant Google has seemingly weighed in on the debate surrounding LGBT rights in Russia ahead of the Sochi Winter Olympics, which officially begins today.

The company has decorated its homepage with a rainbow-coloured Google Doodle depicting Olympic sports such as skiing, snowboarding and curling that will feature at this year's Winter Olympics held in Sochi.

Beneath the search bar, users can also see a quote from the Olympic Charter, declaring that "The practice of sport is a human right."

The quote continues to say that "Every individual must have the possibility of practicing sport, without discrimination of any kind and in the Olympic spirit, which requires mutual understanding with a spirit of friendship, solidarity and fair play."
